Various concentration of formaldehyde solution (1%, 5%, 10%) were applied to cut pulp surface, for 3 minutes and the remaining pulp were carefully examined histo-pathologically. The result were as follows, 1. One week survival group which were treated by 1% formaldehyde solution showed seperation of odontoblast layer randomly and the weil’s zone was undistinguishable. Deeper portion of this area was necrotic or coagulated. 2. Two week survival group which were treated 1% formaldehyde solution showed necrotic appearance spread from odontoblastic layer to weil’s zone. 3. One and two week survival group which were treated 5% formaldehyde solution showed the odontoblastic layer was highly necrotic, under this zone empty net-work was seen. 4.
